There is no pedal in the world not meant to bring us good tone. The Calvin Compressor features an OTA-based, transparent circuit and is a great start to your chain and is ultimately tweakable with five knobs and a voicing switch to attenuate treble frequencies, making it a great fit for electric, bass and acoustic guitars.

When you find yourself Desiring Tone and may even be Obsessive or Compulsive about your Drives, don't waste your pedalboard space. Get yourself a Piper Drive V3, which goes all the way from open, transparent tones to gainy, mid-forward distortion. It stacks beautifully, and it pushes high gain amps into chuggy bliss with an OCD-based circuit.

Westminster Effects The Puritan British Overdrive Guitar and Bass Pedal. Imagine cranking an AC style amp, throwing a treble booster in front of it, and shrinking it down into a box. The Puritan is great for lead lines or as a second or third stage, nontransparent overdrive for Jimmy Page style tone.

Almost all tonal error is really treble muffled. The Westminster Effects Pink Treble Booster gives you back the high end missing in your tone. From clean boost to raging overdrive, the Pink Treble Booster takes its cues from the Dallas Rangemaster, but it also has an expanded range control, allowing you to move from a traditional treble booster to full range boost.

The Chrysostom is an easy to use chorus/vibrato that also happens to be incredibly versatile. With switches for two different voicings and to switch between chorus and vibrato sounds, just dial in the hybrid digital/analog circuit (Which also sounds great on bass!) with two knobs and get warm, warbly tones to classic chorus doubling.
