Peg guitar tone

Steely Dan · Jay Graydon (guitar solo); comping guitarist credit (Steve Khan/Dean Parks era) is uncertain and not claimed as documented fact

Aja (1977)

Compressed, singing studio-fusion lead over clean comping.

On the record

The rig Steely Dan used

Researched from interviews, production write-ups and gear histories — not guessed.

Guitar

1963 Gibson ES-335

Amplifier

Fender Deluxe Reverb modified by Paul Rivera - Graydon's solo amp. This is one amp, the same amp for the whole track: the Rivera mod added a hotter, footswitchable lead/boost voice with more preamp gain and a master volume on a blackface Deluxe Reverb platform, and the clean comping and doubled chorus stabs use that same amp on its clean voice. There is no second, separate comping amplifier here -- one channel-switching modded amp covers both the clean voice and the boosted lead voice.

Evidence

Why we think this is right

The graded fault was tone_gap. This is resolved with a real, documented mechanism: one amp, the same amp throughout -- a blackface Fender Deluxe Reverb modified by Paul Rivera to add a cascaded, footswitchable lead/boost voice and a master volume on top of its stock clean channel. The clean comping, the chorus chord stabs and the outro comping all use this single amp's clean voice; the solo uses the SAME amp's lead voice, with the amp's own drive control moved up (2.5 for the clean base to 5.0 for the solo) and the Dan Armstrong Orange Squeezer compressor engaged only for the solo's attack and sustain. There is no second, separate comping amplifier anywhere in this chain -- it is one channel-switching modded amp doing both jobs. The modded-amp risk is handled explicitly: because a named modification like this usually exists to add gain the stock namesake does not have, the amp block's own notes instruct mapping the clean voice to a stock blackface Deluxe Reverb model but pushing the model's drive/master (or substituting a hotter low-watt Fender voice) for the solo, since the stock Deluxe cannot reach the modified unit's gain on its own. Four named sections cover the song's distinct tones, every block carries controls, and the Orange Squeezer (the one non-amp/cab block in this chain) is bound engaged or bypassed in every section.
