I own 3 OD pedals, a G2D Cream-Tone, Diamond J-Drive and a Lovekraft Mojo Drive. The Cream-Tone gives the most blues sounding tone, it's got a bit more hair and is alot warmer than the J-Drive and the Mojo-drive. The J-Drive is bright, think Strats vs Les Pauls, so with a little tweaking you can get that SRV bite. The Mojo-Drive is my main OD, I use it for gigs and it's the best sounding OD i've ever had so far. I use the middle setting all the time. The OD is clean, smooth not much hair, but you will hear the stereo effect of the Mojo-Drive once you step on it. If i wanted to add more hair I use the J-Drive as a boost, but I loose the stereo effect, the sound becomes more focused, perfect for leads.
I've always wanted to try the Small Fry, but i never had the chance, maganda mga reviews sa net.
