Calling @bongomania! You say here (Keeley GC-2 Limiting Amplifier) The only difference between the GC-2 and the Bassist is one capacitor that causes the GC-2 to react less to peaks in the lows. This means the Bassist will be a more effective hard limiter, while the GC-2 will be a bit less restrained sounding. Apart from that they have the same tone, frequency range, and effect. When you say 'less restrained sounding' do you mean the GC sounds thicker/fatter?
