Hi everyone!

I just got the I beam put in my acoustic yesterday. It sounded good on my amp at home but when I took it to play at a local pub my mate said it sounded quite tinny.

Does that mean now I have to mess around with the EQ on amps/pannels etc where ever I play

OR

Can it be changed on the actual pick up?

OR dit the pro repairer put it in the wrong place or could be moved to a better spot?

Really would love some help, especially from someone who works for LR BAGGS as Ive spent 300bucks and want a good sound NOT a tinny sound =(
