If you've been following the recent posts regarding that Jackson Ampworks Bass Amp that I'm developing, the topic of conversation has recently turned toward the question of whether we should offer a second channel that has slightly more gain, or just add an addition gain stage to the existing 6SL7 channel.

Here is the link to the discussion:

Which would you prefer? Please vote so your voice can be heard!

TBH, when this first idea came about, I wasn't to confident in the design. Now that you seem to have imersed yourself in the bass world, you seem to have a grasp of what a working bassist needs. Any chance you will be posting a final list of specs because I'm gaining interest in this amp.

What about speakers? With 100 watts a modern design high efficiency speaker would be the ticket. Please don't tell us you're going to the trouble of creating a sweet head just to couple it up with another 2x10/4x10/6x10/8x10.

I may offer a speaker cabinet in the future, but for now I'd like to really concentrate on offering the amplifier. Just imagine the discussion that creating a speaker cabinet will involve! :)

I'm intrigued by your request. Tell me more. What specifically did you have in mind? Just a control that blended between the two channels? Or a foot pedal that did the same?

I'm pretty sure he meant an IOD style footpedal that blended the channels together. It's pretty useful for dirtying up the tone on the fly, but i think it'd be impractical with this particular amp. I think a footswitch would be better. but this is all IMHO, IMWO, IME, YMMV, AHSG,HSUHAUOSUA, etc. :p :D

I'd have to admit when it comes to the poll I really wouldn't be able to decide with my limited experience but damn, you guys are building one fine amp, keep it up! I'm glad you've gone up to 300 watts, that seems about reasonable. And it strikes me you've managed to put in everything that any bassist could ever want from a tube amp. Nice!

That's the idea! I want this amp to be the "go to" amp for players that are looking for the best tone and the best features possible!

I had thought about asking for a blend option (you could dial in an overdriven tone on the 12AX7 channel and then blend it with the clean 6SL7 channel for grit, but with retained fundamental), along with a footswitch for Ch.1/Ch.2/Blend. I would find this functionality to be a bonus. But, on the flip side, this might run contrary to your idea of keeping the signal path for the 6SL7 channel as "pure" as possible. Again, it's your call. I'd like the blend feature (and/or the ability to blend in some clean low frequencies to Ch. 2), but your goal of uncompromised tone is also one that I value (above all else, in fact).

As F5F guessed, the SWR Interstellar Overdrive style blending between the clean and dirty (which can be done with a wah-style footpedal) is my feature request.

And yes, setting the "endpoints" of the clean/dirty fade would be really handy.

The blend idea is cool but I'm giving every possible effort to keep these channels separate in order to keep the tone of each channel distinct and pure. I'm afraid that blending the two channels would defeat this effort. I'm like you, the tone has to be pure or nothing else really matters.
