Sending your dry guitar signal to a sound man is a bit like that team-building exercise where a blindfolded individual is instructed to fall backwards into a group of people who might (or might not) catch him or her.
GMF's Ai1 offers guitarists more control over their DI tone, with a preamp and headphone amp to boot. If GMF sounds like a new brand to you, the CEO also happens to be the founder of Ultrasound Amps.
Let’s take a look at the controls: Treble, Bass, Level and Gain. Toggle switches include a Ground Lift, Phase In/Out and a Shape On/Off. Shape is a mid-scoop when engaged. The ins and outs are ¼-inch jacks, a balanced XLR out, ⅛-inch headphone jack and a pair of stereo RCA in/out. The Ai1 can be powered by 9-volt battery or a power supply.
With the RCA ins and the ⅛-inch headphone jack, I was able to jam along with music on my phone. Measurements are roughly 4-by-4-by-2 inches, which fits comfortably into most gigbag or case pockets.
Let's go to the audio clips!
For all the clips below, I used a Taylor 314 I borrowed without asking. Thanks, Dad!
Clip 1: Is the Ai1 straight ahead with a little onboard EQ’ing.
Clip 2: The same as Clip 2, but with the Shape function on.
Clip 3: Some fingerpicking to show off the Ai1’s clarity without harshness.
