R2R Electric OC44 Treble Booster Professional 

Thanks! The amp started as a Trinity Custom Plexi, but I built it with EL84s instead of 6V6s...its Normal channel is about the closest thing I have to an amp that "needs" a treble booster per the conventional wisdom, and its TMB channel is practically a treble booster on its own! The first half the gain's cranked about 2/3 and the 2nd half it's over halfway, and the tone knob is below noon (low pass territory). A lot of people say treble boosters sound the best into a cranked amp--I tried maxing the gain when recording the demo and it was just too much distortion, especially since I wanted to actually turn up and showcase the boost. It's probably a bit tough in a home studio demo to replicate the original use case (a stage-volume rig with a lot of headroom that's too dark)...I think the critical thing is getting the amp gain high enough that the signal is really full-range, and, usually, pretty chubby as a result, especially in Fender circuits, which mostly get wayyyyy to bassy when cranked. It's also received wisdom that TBs don't sound good through American amps but I would tend to disagree, especially with tweed and brown Fenders. For such a simple circuit, TBs have some serious magic, and they're fun to build too...more videos on that topic later :)

Yeah! 12F150B is my fave ceramic American for black panel Fenders. Haven’t tried the 12F150T but the alnico version is next on my list. My next video will be a comparison of the same cone with alnico vs ceramic-the presence range is much punchier and potentially harsh with ceramics, so I would be wary of pairing the reportedly very bright T cone with ceramic.

@@ElliotGKnapp is the 12f150b bright and clear ? I tried a 10f125 and a 10a125, the f is punchier and the a brighter

@@ElliotGKnapp hi, did you try a 12a150t ? Did you record the alnico vs ceramic speaker ?
