The Total Sonic Annihilation 2 from Death By Audio is the perfect pedal if you need a creative spark to your playing.
From DBA: The TSA2 works on a simple premise: what if effect pedals were patched back into themselves? What does it sound like for a filter to be multiplied by infinity? Or if your modulator was modulating its own modulations? The TSA2 creates a controllable feedback loop, causing your pedals to cycle back on themselves, feeding the output back into the input as much or as little as you want. Experience true sonic exploration: every unique pedal array will produce a vast world of textures and possibilities.
FEEDBACK: The big knob. This controls the amount the SEND (external effect input) is forced back into the RECEIVE (external effect output). This creates feedback within the circuit to create new unbridled, experimental effects and results. The more this knob is turned up the more intense and explosive the effects will be. The ACTIVE BOOST is also in this loop and (if engaged) will be forced back into itself to create its own wild and interesting sounds if nothing is plugged into the loop.
ON: In the ON position, this toggle switch activates the ACTIVE BOOST circuit.
PHASE: Flips the phase of the effects loop, only when the ACTIVE BOOST is on.
GAIN: Controls the amount of gain of the ACTIVE BOOST circuit.
LIMIT: Limits the output volume of the entire pedal only when the ACTIVE BOOST is engaged.
STOMP SWITCH: Bypasses the effect.
NOTE: When the TSA2 is turned off the TSA2 is bypassed but every pedal in the loop is still part of your signal chain. Any effect(s) in the loop works as usual.
INPUT: Plug an instrument into this jack.
OUTPUT: The output of the Total Sonic Annihilation 2 is here. It connects to your amplifier.
SEND: Connect this to the input of the effect (or chain of effects) you would like to control and warp. If left unconnected it is connected internally to the receive jack.
RECEIVE: This is connected to the output of the effects in the feedback loop.
9V: Plug a 9V Negative Tip Positive Ring DC adaptor in here. When plugged in it will bypass the internal battery. NOTE: When the ACTIVE BOOST is not engaged, the pedal is completely passive and can work without power.
