Hi there folks. It's been awhile since I've been here but alas, I have another question. Right now my main recording rig is: Desktop PC w/ XP Emu 0404 USB Interface AKG Perception 220 Shure SM57 I'm looking for some type of upgrade. I believe for now my mics are okay, but let me know your INPUT (ahaha) on that. I do all sorts of styles of music. I was looking into perhaps a preamp upgrade such as the ART Pro Channel Tube Mic Preamp. Would this be worth the upgrade? My budget is right around $300.00 more/less. The built in compressor sounded appetizing. http://pro-audio.musiciansfriend.com/product/ART-Pro-Channel-Tube-Mic-Preamp?sku=180589 My main problem right now is getting a good electric guitar sound. I have quite the guitar rig and I'm an experienced player so I know my tone is great and exactly what I want but I am just having a hard time getting it to sound good through my current recording rig. I've tried different miking techniques but am having a hard time getting the sound I want in my recordings. Would this preamp help overall? Or please suggest what you think my next upgrade would be. Thank you for putting up with me!!!
