I’ll help with resurrecting the thread. I own a 60 Watt Marshall JCM600 2×12 Combo that out of curiosity I just re-tubed with four matched and balanced Mullard reissue CV4004s, and two matched Mullard Reissue EL34 XF2s. I also have a 5 Watt Crate Palomino V8 that contains a CBS/Hytron 12AX7 and a GE 6BQ5/EL84, both tubes were 1960s NOS when I installed them. Primarily, I use the Marshall when playing with others, and the Crate gets used for practicing alone if the Marshall is not home with me. I use both for recording since they produce similar yet different timbres.

Hi. There isn’t one, single answer to your question. The best thing is to experiment with what you have, and find out what works best for you. As the responder before me indicated, there are many posts and videos on the web that attempt to subjectively resolve pedal placement, but there are too many variables. Does your amp have an effects loop? Is it serial or parallel, or maybe you have both. Do any of your pedals have effects loops?

For example, my Marshall JCM602 has both serial and parallel effects loops. I put pedals that do not have a wet/dry control in the parallel loop so that I can mix their output with my dry signal. Everything else goes in the serial loop. I use the amps spring reverb, so I don’t have to worry about where to place a reverb pedal, but I would think one would go somewhere at the end of signal chain since that’s where the effect naturally takes place yet, the Turnip Greens allows one to flip the Holy Grail Max and the Soul Food signal path, and placing the reverb first is interesting. Also, I don’t use any overdrive, fuzz, distortion pedals since that is what I use the OD channel on the amp for, but I am looking at the Ram’s Head reissue which I would probably put first in the serial loop, or possibly between the guitar and amp’s preamp valves.

Keep it simple and experiment.
