Thank you for the review. A very interesting tool. The parallel way is now done often in pedals because ist’s easier to transport. But inside the head it has a very unique character
Yes, modern technology has made many improvements since this particular amp was made (1977). As I mentioned in the video, there is a foot pedal that originally came with the amp that allows you to shift all the functions I showed without having to unplug first. I want to get an original unit, but if I can't locate one, then I will have to make one for myself.
Been doing some research on these beasts. Can you run separate inputs into each channel and blend them similar to the parallel inputs? Ie, split your signal on your board, run the effects into the harmonics channel and the clean into the normal?
@@rjbrando9616 interesting question. I hooked up 2 bases, one in the harmonic, one in the clean. The amp didn't care, but signals went into their respective channels and were fully controllable. The output was combined with no problem. It's an interesting sound tonality with dual input. I might have to think about configuring the amp that way for certain songs.
@@tjsogmc I dug up the schematic after I asked this question and saw that there's a summing amp after each individual preamp section. Really interesting. I use an XO Variable Crossover and wonder how it'll handle two separate frequency bands running into each channel then summed. Rad amp nonetheless
@@rjbrando9616 they really did their homework back then. I'm certain there's nothing this amp can't do. I also have a 79 Mark 3 and it had a dirty channel and a clean, not the ful harmonic that the 77 has (no fuzz), but sounds excellent nonetheless. I like the Mark 3 because it has bi-amp output and I like splitting that between my 210 and the 125.
@@rjbrando9616 it has a built in frequency splitter with a crossover so you can send the signal out to two separate cabs, one for highs and the other for lows
