I'm looking for a pedal pre-amp, and I'd like it to be polivalent and have some distortion as I'd use it sometimes. More or less they cost the same. I had a Sansamp and a Valvedrive and I didn´t like them... I must recognice the Tronographic has some advantage because I like to use things that little people has... Which of these two? The bass is a Ibanez with Nordstrand Big Singles, downtuned. Thank you!
