Hi guys, I bought a Marshall Haze 15 two months ago and I'm loving it so far. I love the onboard gain, as well as effects. However, I am thinking of having the head modded to have an effects loop. This is because I want to have some pedals in between my onboard drive and effects. I'm pretty sure it can be done, as the Marshall Haze 40 has an effects loop. But who can I approach to do this?
