I'm looking at getting a pedal to boost my mesa and tighten the bottom end up. The TS-9 is the standard for this use. How does the TS-7 compare? I noticed that it had a switch for the TS-9 "mode". The TS-7 is only $40, so if this one is comparable then I'll buy it instead the the TS-9. Any input would be appreciated.
They both have an almost identical circuit, the tonal difference comes from the quality of the components used. If you're only using it as a boost the TS-7 will suit you fine.
