I know exactly where your coming from! I to am a fender through boogie kinda guy(strats and tele,s) When i use my mark 3,s there is no problem with sustain but the .50 caliber just doesn,t quite cut it imo it,s voiced more for rock with gain levels to match! There are several options you can use when it comes to pedals....option 1...try using a tube screamer as a clean boost...option 2...use a clean boost eg a keeley katana...option 3.....use a dedicated distortion pedal, i personally combine option 1 and 3 and use a ts-9 tubescreamer set up as a clean boost into a keeley modded ds-1 for a dual high gain lead pedal set up! My strats and tele,s sustain no problem with this set up! Many people like the bb pre amp pedal but although it has a smoother lead tone( than the ds-1) the difference is not that amazing that you could pick out which is which with out a/b ing the two pedals and imo the build quality of the ds-1 is much superior to the bb ( the bb pre amp pedal i tried arrived faulty in the post) and the ds-1 is a more convenient size for pedal boards ( i use a boss pedal board!) hope that helps.
