+1 would add essentially a third option (not including GEQ) on the footswitch.

Give me a Deep Switch on a Mark V Ch3. But don't tell anybody I asked you! :lol: :wink:

MT-

It would be cool to swap out a pair of 6L6s for EL34s. You couldn't make a non simulclass amp into a simulaclass amp without an OT replacement, but you could rewire for one set of EL34s instead. Running a set of 6L6s and EL34s would be very nice for all of us that don't have a simulclass amp. If you didn't like the sound, you could always switch back.

:D That's not a bad idea, I'll have to work on that!

We have an illness in the family that will delay the mod kits, but keep them coming. Once things settle down a bit, I'll get right on them.

I am a DC-5 owner.

I would also be very interested in:

-DC-5 reverb mod for better reverb

-5-way Midrange Sellector switch for channel 2

-Footswitchable (adjustable) Solo Boost

-but I would also be interested in some kind of a mod for more gain on channel 2, or even a way to just tighten up the current gain channel.

Buy Monsta Tone mods!!!

If I end up keeping my DC-5 I might be interested in these also.

I think if you get Mk 1 reissue schematics, that would help you, because the re-issue can use 4 x EL34 s, 4 x 6V6's, or eurotube guy said 2x e34l's plus 2x 6L6's

Links to the schematics :D

I'm definitely thinking about the following though:
Variable NFB
Lately I had played a Triaxis in the FX return of my MkIVa amp and noticed something curious. When I footswitched between the three amp's channels, I heard that the sound changed when I selected the lead channel. It became bigger and bolder. I suppose it has to do with the poweramp, since the amp's preamp should be almost completely removed at the FX return jack. If you found me a way to add a switch which could make me activate that "supposedly-poweramp-feature" for the Rhythms, I'd pay you a hundred bucks for a cap. It's just that good. :)

Maybe this is a completely stupid question :oops: and not at all possible but
could you somehow replace the mid and bass pots on R1 and R2 with
pushpull pots on a MKIV and wire them so that R1 and R2 have seperate
mid and bass controls? Please don't laugh at my lack of electronics savvy!
Thanks!

That could most likely be done, but it would take another LDR to remove the existing bass and mid when R2 is sellected.
Also, it would have to be concentric pots which would basically have 2 knobs in the place of one.
That's not really something that I would want to have as a kit, maybe though!

But it's something you could do if a MKIV was sent to you?
I don't have a MKIV right now but thinking about it.

I don't see why not.
The only thing is that the clean channel's mids will be more present and you will have to make sure you don't turn them as high as you normally do unless you want the extra gain.
The reason for this is that the only concentric pots I can find are 25k/25k, 250k/250k, and 500k/500k. This means that the 10 k pot that the amp had before will now be a 25k, and this means that there will be tons more mids available if you turn it up.

How many of you guys would want to see mod kits for your Mesa amp?
I know that shipping is a mother and there are lots of DIY guys here.


What kits would you want to see???
Thanks for asking.
I'm sure i'm not the only Stiletto Ace owner who would like to re-voice the gain channel for less brittle fizz, more chunk.

I can definitely do the Stilleto mod, but it's not something that I can put in a kit just yet.
I think you're the guy who emailed me, but if not, let me know if you're interested in sending it in.

I am starting to ship out mod kits for the following amps:
DC series:
More gain
EQ footswitch on the front of the amp with the Channel - you have to find a DC (series B) footswitch for now
Better Reverb for version A
Bias Pot
Negative Feedback - 2 position switch or variable pot

Heartbreaker:
Better Reverb
Bias Pot

Blue Angel:
Fender style input jacks
More Gain
Fender style Bright


I'll have more to come, but some of them will be pretty dificult, so I'm not sure how far I want to go with this.
