Thanks for listening.

Edit: From my other thread.


Update:
Made some changes to the normal channel to tighten up the bass.
Changed coupling cap to .0047uF
Changed cathode bypass cap to 3.3uF
Sounds much tighter now. Really has that 80s feel.

That's correct and It sounds good that way by itself i.e. normal channel only. I only changed it because I have the cascade switch and the low end was a little muddy when cascaded. If you do not want the cascaded channels then I feel you should leave the normal channel as is. I am trying to keep the versatility in the amp in that I would like the "darker" normal channel for clean to slight breakup, the "bright" channel for more moderate gain and the cascaded channels for high gain. Trying to find that balance in the normal channel so that I have good low end for clean sounds but not so much that it gets loose when cascaded.

Great amp and great playing. I cant believe you can get that sound without any pedals.

Sounds really good! Very tight!

Are you still using the stock recto and stock filtering?

Thanks. I really need to post some new clips. These clips were made when I first built the amp. Lots of tweaks since then. Also there were some questions about my pickups. I did not realize it but it turns out that the Duncan Distortion is one of the "Hottest" pickups you can get with 16K resistance . I measured my other pups and the lowest one I have is 14.8K. So yeah, I am really pushing the front of the amp with hot signal.

Yes EZ81 and stock filtering. I did change the filtering on the board from 16uf to 22uf at one point. It tightened up the preamp a bit but also lowered the gain a bit so I went back to 16uf.
