Hi All I've been trying to work out a cheap Pedalboard effects BI-amp system (got a main board with a really cool but £££ dual loop with lpf & hpf but I'm trying to equip a low cost back up). I've got an ABY at the beginning with phase inverter options which works great, then each line goes through a separate graphic EQ (to make a rough low vs high frequency split) + appropriate pedals. Finally they go into another ABY working as 2 into 1 (pedal blurb confirms it will work in this fashion). But when the 2nd ABY is set to Y mode the signal gets dirty and quiet. I've tried switching phase but to no avail (A to Out and B to Out sound fine independently). I'm sure I'm missing something so I'm reaching out for some advice.
