I recently got a hollow body bass, and I notice its louder than my jazz bass when the amp is at the same volume. Also, the g string will feed back at times, which is odd. So I never have really messed with compression before, but this sounds like an instance where I would probably need it. Does anyone have any suggestions on compression pedals that are light on the wallet? I see that sansamp tech 21 has one that is nicely priced.
