For awhile I have been trying to get the best sound possible to my in-ears and FOH. I've experimented with mics, pods, eq's, preamps, etc. The best sound I got was by running into one of Fdeck's HPF filters, into a sansamp VT2 pedal, into a DI box, to the board. Sounded great but, I hate all that clutter and extra wires. So, I talked to Mike Putnum of Putnam's Guitars in Lockport NY about doing a custom rack using these 3 elements AND also an added semi-parametric mid control to adjust to any playing situation. I took delivery of this rack unit yesterday and brought it directly to the gig. It worked like a champ without any hassle. Aside from the 3 pieces inside, mike designed an adjustable mid control that is about 1 octave in width and is adjustable from 100hz to 1khz. I've always thought that the VT pedal needed some extra thickness in the middle to make it sound like an actual svt or any amp really to the board. The mid control on the vt is supposed to be 500hz but really, it is more like 1khz. I found myself boosting the new mid control at 500hz and it really made the di sound more like my live rig. The unit can be powered by a 9v adaptor or phantom power from the board, has a ground lift, both 1/4" and xlr in/outs. It's designed to be operational and useful in any situation. In short, it's a real life gig tool. I just love the sound of it in my in-ears and out front. Last night we had to be very low volume so, my sound was about half front of house and half my rig. It sounded like I just had a mic on my cab and was using it for alittle clarity out front. It sounded like a mic on my cab in the in ears but, without all the mic bleed and room noise. My drummer actually commented on how clean the in-ear mix was. Im sure alot of guys would love this mid circuit that Mike designed for me and this rack unit in general. He did such solid work and for a very fair price. I have no complaints. I had the unit in the basement today and was playing through headphones and I actually prefer playing this way than to use an amp at home. It sounds better and I don't bother my cranky neighbor.
