I'm trying to do a clean boost on my acoustic pedal board before a pre-amp/DI. But what I've tried so far alters the tone too much for my liking to be used in the middle of a song. What I'm using: The pre-amp/DI is the Behringer ADI21 V-Tone (https://www.sweetwater.com/store/detail/ADI21--behringer-adi21-v-tone-acoustic-driver-di-pedal). I picked this up earlier this year on a whim when I saw a used on at Guitar Center. I like it -- it gives enough tone shaping as well as a nice clean balanced signal so I can send it to a mixer or directly into the back of a powered PA speaker. For the boosts, I've tried two so far. The first is the Mosky XP Boost (which is a knock-off of the Xotic EP Booster) (https://www.amazon.com/dp/B01D4FY0BC/?tag=tdpri-20.). Now I fully understand that this pedal is designed to color the tone as it's based on the preamp of old EP-3 echo machines. But when I use it with my electrics into a clean Princeton, and have the pedal's internal bright switch engaged, the change in tone is minimal. But with the acoustic set up, it creates a much fatter tone with less presence. Last night I replaced the XP with a Marshall Ed the Compressor. I turned the compression all the way off and just upped the level knob. With an electric guitar into a tube amp this gives a straight clean boost. With the acoustic, it again fattened things up. It was similar to what the XP boost did. I didn't A/B the two pedals but I liked the Comp better. Now, with both boost pedals I like the tone. It works great on songs where I'm finger picking or playing lightly for the duration vs. bashing out big strums with a pick. The problem is if I want to give a slight boost for lead or a quiet section in the middle of a song, the guitar sounds noticeably different - not just louder. I should add, I'm not going for a huge boost -- really just enough to get the more lightly played sections equal in volume to strumming. My acoustic has an active preamp but does not have a volume control. I have one more boost pedal I can try, an old Rocktron Austin Gold which is almost completely clean when the Gain is set to zero. I doubt this pedal would work long term since it always has a tiny bit of OD/distortion in it but should help test whether my issue is the boost pedal or how the Behringer pre-amp is reacting to the boost pedals. So now if you have read this far: Has anyone had issues running a boost before a pedal based preamp/DI? This could be acoustic but I'm curious if maybe the same happens with electric.
