Most of amps feature the effect loop (FX LOOP) what enables to connect various guitar effect. The signal level varies in different amp models (from 0,3 to 15 Vpp) what can substantially affect the effect tones.
In terms of signal level the guitar effects are grouped as follows:
- designed to work directly with the guitar (for signal from 1 to 2,5 Vpp)
- designed to work on the ‘professional guitar effects’ signal level (4dBV i.e. 4,6Vpp)
- which have the gain adjustment and can work in both mentioned signal ranges
Not matched signal level mostly brings the overdriven sound (sometimes called "sound’s dynamics limitation") and higher hum level. ALA-1 enables precisely ‘matching’ the signal level of connected effects.
The other problem which occurs especially in older models of tube amps is the high impedance of SEND output. Connecting longer (few meters) cables brings hi tone loss.
Thanks to innovative circuit solution applied in ALA-1 this problem is completely solved.
Additional advantage is only one cable for transmitting SEND and RETURN signal (one ‘from amp to pedalboard’ cable less) which solves the problem of ground loops caused by SEND and RETURN signal cables.
