The Glow Series includes 3 analog solid state amp tone/overdrive pedals voiced for specific applications that truly sound like a tube amp even when plugged directly into a PA.

Whatever the configuration; pedals upstream, downstream, direct into a PA, a guitar amp, DAW, or whatever, “Glow Pedals” will have you rethinking how guitar sound is done.
