I have a SpecOp and I really like the voicing but there are several things about the tone that I dislike. I was going to mod it myself but I can't get a schematic. I tried to contact Diamond, but I never go a response. I know that they are dealing with the aftermath of hurricane Harvey. No...
I know this topic is a little silly and is totally subjective. I'm fishing for opinions because I'm having a hard time deciding what amp to buy. Also I know he played a Metalhead Modded JCM800. Used to own a FJA FD Marshall. That amp was killer but it didn't resemble that album tone at all...
I can't find a clear schematic for this thing anywhere. Bass, mid, treble, and pres is not responding. All resistors and electrolytics check out. Stumped so far. I think it may have a bad pot. Ideas?
I figured out that R31&32 were 100 ohm. I figured out that I had a burnt screen grid on V5 and Jerry helped me figure out the parts on the fs pcb. The amp is playable. It's still not switching channels. It's stuck on the od channel. I don't know if it's on od1 or od2 but it sounds bad ass! I...
To be fair, Scott said that he didn't have schematics for these very early Pro Mods. He also said that footswitch design was flawed and would need to be replaced completely because it would eventually fail again. The new footswitch boards are not compatible with these older amps and every board...
He said he never created schematics on his older amps. I did the best that I could with the pictures that are on google but I'm looking on a small laptop screen. I just want to make sure I have the correct values in place. I have something wrong though because bias voltage(with tubes pulled) is...
I just purchased a Splawn Promod that has a few issues. It's an older model('05) and Scott doesn't have schematics for older models. I know it's asking alot but can somebody snap a pic of R31&32 and of the footswitch board? The only ones that I can find on google are too blurry. Thanks!
I already know how to hotrod several amps. I'm trying to experiment with some with circuit design before I do my own designed build. I need to lean more about high gain really.
I went a little overboard with the term "gutted" but the circuit will be modded and reworded several times before an eventual gutting. I just need a super cheap subject amp for learning purposes. I went with the BV120. I have an old Traynor coming in for a repair next week. Maybe it's a decent...
