And I had flangers before and after the pedal. So this is what I mean - the boss SP-1 is one of the most reactive pedals you can get. It is well worth the price, and is especially designed for virtuosos and guitar geniuses! I love using mine on my Bass Guitar personally.
The SP-1 is a parametric equalizer with one frequency band only. The spectrum knob sets the frequency range in the interval 500Hz to 5kHz. The balance knob sets the peak within the range. The SP-1 was more popular with keyboard players than with guitar players.Today it is one of the most sought after collectors items and a mint condition SP-1 doesn't come cheap. I have photographed my favourite setting on a Bass Guitar - when paired with overdrive. The BALANCE knob gets extreme, and the phaser-like effect of the SPECTRUM knob becomes a lot more ovbious when the BALANCE is turned high. Think of it as an EQ that shifts phase in an extremely analogue-like way.
It is a tube screamer, EQ, modulation all in one! You just have to make use of the extremely simple 2 knobs in creative ways to invent new effects! This pedal is definitely sought after for a reason.This item is in the category "Musical Instruments & DJ Equipment\Guitars & Basses\Parts & Accessories\Effects Pedals\Other Guitar Effects Pedals".
