Here is the interior of my TB-202. I'm wanting to mod it in a couple ways, but want to know how easy it would be, or even worth it (it's a $250 unit).
First thing I noticed is that, though it's a two channel unit, there's only one tube, but a place on the board for a second. I've not yet graduated to building my own tube gear yet, so I don't know if adding that second tube would help much or be difficult to do.
Secondly, the eq is a 3-band fixed freq. (+/- 16dB @ 80Hz, 1.8kHz, 8kHz). How difficult would it be to make the mid freq. knob a sweep and the high freq. the gain for that sweep? I'd like to keep the low and select the other to be between like 120Hz-10kHz. Actually, any sweep range would be better, but whatever's reasonable.
...and now the money shots :grin: :
