Title: Thunder Cannon (BMP)
Post by: greyscales on August 14, 2012, 07:06:21 PM
I started doing a few pcbs of my own lately to get my commercial stuff going. This one is a modified BMP with a mids pot and clipping switch. Sounds better than I could have ever imagined.
The tone stack is slightly modified to go from a slight mid scoop to a big mid boost with a lot of range in between. Still need to find the right taper for the controls, but this one is better than the prototype.

It's hard to see, but there is some stamped lettering on it. The clear coat fades it for some reason.

Definitely couldn't have done this sort of thing without everyone on this forum. Thanks, guys!

Very nice.  Is that your pcb design? Tidy layout :)

Yes, I designed it. I'm probably going to change it next time around but it works pretty well. Might go with 1/8 watt resistors only.
