This mod works in the following (and likely a lot more Peavey products):

Profex
Profex 2
Bassfex, same as a Profex 2
Transtubefex
Tubefex
Session 2000
Transfex Pro amps
Autograph equilizer

I feel I need to explain the batteryless mod a bit further. There is a 28 pin memory chip in the units that holds the user settings (typically Newman settings). This chip needs a battery to hold its memory when power is off. I remove the battery and replace the 28 pin chip with a non-volatile chip. It will hold your user settings with no need for a battery to back it up. This elimates the battery in your unit forever.


I am seeing more and more units coming in with battery damage and obvious problems in operation. I am limited to the repairs I can do on a Profex 2/Bassfex. I do not repair Tubefex, Transtubefex or others, I just do the battery less mods to them. If your unit needs further repair I will be glad to send it over to Mike Brown and the boys for expert repair! I have done so for several already. I supply them your billing information and they take care of it from there.

I can get your units out usually the day after they arrive. It is easiest for me to repair and ship back and then bill you via email. No need to send payment in advance.

The price has now incresaed 50 percent due to the fact theses are the last of the chips on the market. I had to order 100 to even get that good of a price! My distributor is out, ZMD will not be making any more NVSRAM chips and the last of them are in the hands of one or maybe two (one still uncorfirmed) surplus parts houses.

Effective immediately my prices are increasing to cover the cost:

Option 1:

$45.00 for the chip, reload your settings or I can reload from my collection, repackage and ship. I have a nice combo of Jeff Newman and Jeff Peterson settings I can load. You do not lose any Newman settings, just the some that were duplicated.

Option 2:

$50.00 for the Burr Brown chip upgrade, Profex 2 and Bassfex only. The result is a lot less background noise and a sweeter sound. Four chips are replaced with this mod.

Option 3:

Total is $90.00 for both of the above mods for Profex 2/Bassfex.

Shipping charges are additional . I will send an invoice in Excel format and include a copy with your upgraded unit.

I am adding a $2.50 handling charge to cover the cost of shipping tape, running these items over to the post office on occasion, bubble wrap (some units are requiring additional packing), shop items (Q-tips, denatured alcohol and such).

Here are other things I can do for you:

1-I can replace broken pots for $15.00 each (volume on the front or rear only for Profex 2 or Bassfex and only at this price if the unit is sent for the the Burr Brown and/or the battery-less mod), also power supply input jacks for same (have only seen 2 bad ones in all the years I have worked on the units). I keep the pots and jacks in stock.

2-Knobs are $3.50 additional.

3- I can also replace the battery in your cache card, if needed and reload the settings to it for $5.00.

4-Output mod to accommodate a power amp/rack system, doubles output voltage! This is a $5.00 mod as long as you are doing the battery-less memory chip for Profex 2 /Bassfex only!

5-Power supply (wall wart) for Profex 2/Bassfex at $15.00 and shipping. I have a limited supply of Basler 16.5VAC transformers with the correct 2.1mm power cord. This unique transformer also has screw terminals for easy cord repair or replacement. I have used these in my shop and also sold many in the last few years.


-I do not need your power supply sent with the item, I have several here already.

Pack to protect the racks ears! They bend easy in shipment. Try to pack so the item does not shift. Items packed in peanuts will move all around and bump the ears. I have seen many damaged this way. Wrap in bubble wrap for best results.

Personal check is fine. Postal money order works, too!
If you use PayPal I must add about 3 percent to cover the fees they charge me.

Just got this shot from a member of the Yahoo Groups, Tubefex Forum.
This is a picture of the typical damage to a Tubefex from battery leakage, click on the picture to enlarge:
http://community.webshots.com/album/470230867FPxOhL

They seem to get the worst of it, as the battery end is so near a voltage rail! Only slight leakage is needed for this to occur.

Bottom line, check and clean the battery before you get this problem (blown components and lots of smoke).

Got another 100 Burr Brown chips coming this weeks! Takes four for each Profex/Bassfex modded. I have plenty of battery-less memory chips for now. I also have 2 cache cards ready if any one is interested ($90.00 each loaded with Newman/Peterson combination of settings).

If anyone had a dead/non-repairable Profex 2 or Bassfex for sale let me know. I could use a few for spare parts, as some of the parts are no longer available.


Below is a link to pictures of some damaged units I have repaired. This is typical from excessive battery leakage. All batteries will eventually leak on these units!

Hey guys and gals, I just got back my ProfexII from Ken. He did the batteryless mod and Burr Brown chips upgrade. WOW!!!!
Much cleaner, quieter and I never have to worry about battery damage from a bad battery. Some of the best money I've spent on equipment. If you have one of these units or Bassflex you better git'r done before it is too late and something gets ruined. Not to mention the better sound.
Count me in as one satisfied Ken fox customer.

Hey Steelers,


Just wanted to drop a few lines your way about Ken. He does a GREAT job at improving
an already great unit the Pro-fex.

I bought a unit from ken several months ago and needless to say I have had NO PROBLEMS whatever with it.

Thanks Ken for your untiring contribution to the steel guitar industry..

Just wanted to let everyone know I am maintaining two residences till about next June. I got married 3 months ago and have a second home in Daleville, Alabama (20 miles west of Dothan and three hours from Ray City).
I spend most of each month here. I do work at both places. Please let me know when you are sending a unit and I will advise which address to send it to for the quickest service.
The post office holds my mail in Ray City till I get back, so it is safe if it goes there while I am away. I am usually back every 1 1/2 weeks for about 3-5 days to take care of bills, lawn, pool and such!

Thanks again for all the business from my fellow Forum Members!

I have been asked seveal times about doing work at the Dallas Show this year. I did so many there last year that I was only able to catch a few hours of the Saturday show!
This year I plan to attend the show and not do any work on units. I will be driving out to Dallas and visiting my step-daughter in Oklahoma City. I will be glad to take units back with me and ship them to you after I get back.
Just got in 100 Burr Brown chip and have a good stock of the batteryless memory chips on hand. My turn around time is typically same day. I ship USPS Priority mail only! 2-3 days and it is back safe and sound, I am a UPS shipper but hate to use them unless it is a last resort! They are just too rough on packages.

Are you going to be at Saluda? Are you going to have a table there? If not, how will I be able to find you? I plan on being there Sunday and bring my profex for the bat and brown mods.

I will still be working at both the Alabama and Georgia homes thru the holiday season, no plans to travel. Freight will probably be slow during that time with all carriers, though.

I would highly recommend post office during this peak season. UPS is never too careful to start with and it will be worse with all the temporary help they hire during the holiday rush!

I just ordered another 52 memory chips this week, I have a few left if anyone has a unit coming soon.
I am selling a lot of memory and Burr Brown chips now for install by customers as well. This is especially good for folks overseas! I have sent chips to New Zealand, Canada, Ireland, Norway, Finland and other places now! So far all are doing a great job of getting their units going with a little help from my end. Glad to help out!

Hi Ken,
I just wanted to thank you for the great (and speedy!) work you did on my 2 Profex II's.
We're in the middle of our Canadian Christmas tour, and the mods are proving to be the tremendous upgrade you promised.
Worth every penny. =)

Thanks for breathing life back into some very road weary gear!

Just got in 52 more memory chips today. That last batch went pretty fast!

Thanks to all who have ordered chips or sent units for repair.

I can still get the units out typically same day they arrive. Freight is a little slower now with the holidays, keep that in mind.

Hi Ken, I successfully upgraded my steel playing friends Profex just last week and he loves it. I got a call from Warren Neilsen in Australia last night too so you may hear from him shortly for a batteryless chip as well! Keep up the good work mate.

I have enough Burr Brown chips for about 5 more mods. I have a good stock of batteryless mod chips left. I now have a memory chip for the ADA MP-1 guitar processor. Per a request from a Canadian user and folks on the ADA Processor forum we have tested a chip to get rid of the battery in that unit. This is an older processor and not sure anyone here would have one, just wanted to throw that out there.

Thanks again for all the business this year! I have had a great time getting the units updated and met a lot of new folks along the way.

Thanks, Bobby!

Plenty of battery chips still in stock at this time. There are 9 Profex units supposed to be on the way now for upgrade.
Should be in good shape on the battery eliminator memory chips. I am running low on the Burr Brown chips and will re-order soon, if there seems to be more interest coming. It only takes a week to get them here from my supplier. I have to order at least 100 at a time to offer the low price on that upgrade! Let me know if you have a unit coming and are interest in the Burr Brown chips, so I can place an order soon.

Thanks again!

i just got another one in from a Forum member with battery acid leakage. The acid had ran under components and clear over to the edge of the board! It took over an hour to remove components, scrape and clean residue and then re-install components on the board. This one came in dead! I was able to salvage the unit. It is impossible to warranty that all acid is gone and there will be no further incident/damage. All one can do is get all they can off the board and components.

Hopefully yours has been done or will get done before this happens. I believe that all these batteries will leak in time. Unfortunately I am seeing more and more coming in with damage.

While I make every effort to get the unit up and running, I can't spend hours on them. If it looks as if I can't repair it in a timely manner, then I will call you and offer the option to send it from here to Peavey for repair.

There is no guarantee they can repair every unit they receive either. Their policy has also been not to warranty any repair for units that have had battery dameage.

Got a real scare today! I went to order Burr Brown audio chips for the Dallas show and ever distributor for Texas Instruments was out until mid April!

Ouch! I did a lot of research and found 5000 in Chine. I really did not want to import them.

I just located a parts house, not a distribitor with 5000 in Florida. I got 200 ordered and on the way. It takes 4 per unit for the upgrade. That will cover 50 Profex 2 or Bassfex units!

I only have 16 left in stock today, so that will cover 4 more units. I should have stock next week.


Please remember to include your name, address and details of mods you need. I get one every now and then from a shipping center and no personal info! It can takes hours to track down a phone number and email! I had one unit that was here over 6 weeks before I could locate the owner. I keep track of every email I get, but sometimes that can so sideways as well!

Had a great time at the Dallas Show. We did 49 batteryless chips and 108 Burr Brown audio chips while there!

I got in a shipment of 52 after the shown and am down to 38 already. I still have plenty of the Burr Brown chips, last shipment was 200. Over half are gone at this time.

Thanks again to all who have had this work done!

For both the Burr Brown chips and the battery-less memory chip the total is $55.00 shipped Priority mail.


Shipping charges for installs are additional
and I will send an invoice for the repair in Microsoft Excel format. I will also print a copy and include with the shipment.

Here is more I can do for you:

-I can replace broken pots for $17.50 each (volume on the front or rear only for Profex 2 or Bassfex), also power supply input jacks for same (have only seen 2 bad ones in all the years I have worked on the units). I keep the pots and jacks in stock. Replacement knobs are $3.50 additional.

I just ordered the last 39 memory chips that my distributor had in stock. If they get more it will be 8-10 weeks I am told.

If you need one done the time is passing quickly. I am not certain how long I will be able to get the chips.

Hi Ken. I have a transfex pro amp with a ttf in it and I'm thinking about putting the battery replacement chip in it. I'm good at soldering and electronics and I justg need to know the procedure as far as removing the battery. When I take it out do I need to do anything else other than replace the old chip with the new one as long as there is no battery damage?

Or is that something you don't provide? I wouldn't mind sending you the unit but I think it would much easier for me to do it. I wouldn't mind paying the full rerplacement price if you would give me instructions on the steps of replacing the chip and removing the battery.

Now if this is not something you like to do that's no problem I can remove the chassis and send it to you but I'd rather not.

Bob, email sent with instructions.

I do not recommend anyone doing a chip change unless they are comfortable and familiar with changing IC chips out and also has basic understanding of static protection.

If someone feels they can do it, I will send the chip and instructions. Most every one I have sold so far has resulted in phone conversations and/or emails to assist! Still, I will sell the chip and try to help out. I enjoy helping out and would rather someone call me before they put the chip in backwards, bend the pins up on the chip, etc!
Yes, those things have happened. I have had to replace several chips already that I sent out. I have not had one failure in over 400 I have installed so far. Still a bad one could slip thru the cracks and may have to one of those customers. Still, I replaced them at no cost to the customer. There has to be a small failue rate I would think!

Just got in 39 more chips. Let me know if you need an upgrade.

Just a not, they do not work on the Peavey Midi-filer! I tried them in mine and got data errors. They are working well in my old Peavy Autograph units for sure.
