The signal is split after the pre-amp: one path remains "dry" through the amp, and the other, parallel signal is sent through the effects loop - its return, the "wet" signal, summed with the dry signal in the amp. To keep these dirty little effect boxes as far away as possible from the amplifier's pristine signal, some amp designers started incorporating parallel effects loops. There are a whole host of issues that may corrupt the signal, and the more effect units one chains together in an effects loop (or in any signal chain), the worse these problems may get. This became more widespread with the advent of digital effect processors because, although many love the sound of digital effects, some cringe at the thought of digitizing the dry guitar signal.īut it wasn't just digital effects. Unfortunately, many vintage pedals and rack processors suffered from the dreaded "tone suck" - a rather non-specific term, like so many used by musicians, which encompasses a wide range of issues. This is illustrated (in its most basic form) here: Stop the Suck If no effects are connected, the signal passes straight through from pre-amp to power amp however, inserting a plug into the effects return jack interrupts this signal, so that it passes through the effects loop instead. It used to be that all effects loops simply inserted the effects inline, or in serial, between an amplifier's pre-amp and power amp sections.
PEDAL BOARD SPLIT SIGNAL PATH HOW TO
In this article, I will attempt to explain how and why they are different from a normal serial effects loop, as well as their not-so-obvious problems and how to deal with them. Parallel effects loops have become common in recent years, particularly on higher-end guitar amps.
