I play at a fairly large church. I have to run direct and use IEM's. Here is my signal chain: K-Line Springfield>polytune>TS(buffered)>Timmy>Klone(buffered)>Ampli Firebox>El Capistan>Eterna reverb>Radial passive DI(xlr in)>SBD. I don't know which of the other pedals are buffered. The iems are running off a wired pack, and the guitar is wireless. More often than not, my tone is thin and fizzy. I turn on the TS and it sounds very grainy/fizzy even at low gain settings. I get the same thing with the klone and Timmy. I am happy with the amp sim and cab IR from the Firebox. I'm currently using the Deluxe sim with the twin deluxe cab. My rig sounds great when I dial it in at home. Sometimes, possibly depending on who is behind the board, my rig sounds amazing at church and has all the punch and clarity that I expect. I don't want to be the guy that is always complaining about his direct tone.The distance from the sbd to stage is probably 100 feet. I need help figuring out how to remedy this problem. Thank you.
