Customer Question

I have a Bose L1 system (older one with the horseshoe shaped base)...I use a TC Helicon Gxt voice processor and some guitar effects pedals. I currently run two acoustic guitars through an A/B box run directly into the "in" slot of the TCH Gxt and output both channel 1 and 2 from the TCH into the Bose...with the presets on "0" so I get only the mix from the harmonizer (TCH)...I've recently run two electric guitars (a tele and a casino)(replacing the acoustic guitars) into the system using the same set-up and am getting very poor sound quality from these decent electric guitars...any recommendations for improving the sound quality?

Hello and sorry you're having problems. The AB switch- are you trying to run both guitars simultaneously through this switch? If so, then you have out of phase cancellation from the two guitars and would instead need a small powered mixer to insert between the guitars and the Bose.

If you're unsure, then remove the effect pedals from the mix and run both guitars through the AB switch to the Bose- is the sound quality still poor?

If so, run each guitar to the Bose one at a time- if the sound quality is decent then your AB switch is the cause of the issue and you would instead need a small 2 channel mixer.

Let me know what you find.
