I've got a TE SM-7 eq pedal that I love. Preshape 1 is a basic ingredient in my tone. The only problem is, it's a bit noisy, especially when I use a cab w/ a tweeter. I've been thinking about getting a TE preamp in hopes that it won't be as noisy as the pedal. Does anybody know which models have the Preshape 1 and 2 buttons? TE users, are your preamps quiet? I've been wondering if the noise is merely because the treble is boosted w/ preshape 1, and that there is no real way around it.
