Hi everyone, my bigsby b7 and vibramate v7 are going to come in next week and im very excited to install it on my les paul. But i am in a dilemma. Do i absolutely need a roller bridge of some sort to increase tuning stability, or the difference is not drastic compared to a tune o matic, which is on my lp now. Im not a heavy handed bigsby user, very subtle pitch change (1-2 semitone). Any advice is appreciated!
