Hi all!
Recently I was taunted to try the Baja AFD, which I liked very much. So I said to myself that I would try a few more of Bajaman's preamps - on the breadboard at least. The first one was the EVH Overdrive, but althoug it worked fine and was well-behaved noise-wise (like the AFD), it didn't really do it for me. Also tried the "High Gain" Mod from MTK, but with that it turned too hissy for my ears.
Next, I put the Baja MDR Overdrive on the board:
This one I like again! Also not noisy. Bone-dry distortion. I never played an MDR amp, but the "pedal" sounds awesome.
I'm wondering if any of you have any idea about a mod or two to try while the thing is on the breadboard?
So far I've tried a little bit:
The vero layout for the AFD was a bit of a pain, because everything goes to VREF. The MDR does the same. So on the breadboard I tied all the cap legs that go to VREF together and put them on an SPDT on-on switch (pin 2). The other pins of the switch go to ground and VREF. Switching between the two didn't cause any difference in sound. So when I do the vero I'll use that tidbit for an easier layout.
Other things I want to try:
- change the TL062s for other oamps like LM833
- pull the hard clippers to see if the MDR clips without them
Any other ideas welcome!
