Re: Pedals=second rate tone, mediocre sustain
The question has been answered, but I'll add this comment...
There just aren't a lot of secrets left to getting good tone. Most of the players who inspired us to play, played good guitars through tube amps.
Despite that, the question gets asked over and over ... "I'm not getting the tone I want with my '_________' SS amp. No, and quite simply you won't, and even if you thought you could, you will never replicate the feel, the touch response of a tube amp.
(I know that some amp modeling fans will say I'm wrong, that the newer amp modelers come close to the feel of tube amps, but I'll have to have pretty convincing evidence. No flames, please.)
There is another advantage of tube amps, which is that if you understand the way they operate, they are tweakable over a fairly wide range - by using different tubes and adjusting the bias, you can voice an amp to play cleaner or more overdriven to suit your style.
and there are decent affordable tube amps out there, like a used Fender Hot Rod Deluxe, '59 Bassman reissue, or blackface or silverface Bassman heads, which with a little tech work will be pro gigging gear. I mention Fenders, because that's what I know best, but others can tell you different brands that have affordable tube amps.
BTW, my two DS-1's that John modded are a couple of my favorite distortion pedals. I'd consider doing the mod, which is pretty affordable, before selling the pedal.
best of luck in your quest.
