OMG! I've had her for almost 2 wks and can't pull myself away! Pumped through my M20 and H30 Heritage loaded cabs, the tone is something from Heaven! The finest channel switcher I've come across in over 25 yrs! Jazz, country, blues, classic/hard rock, metal...it does it all in its own way. Ch. 1 is his Custom 80 crkt and ch.2 is his HG crkt. I've always been a Custom fan, now with the addition of his HG, I've got all my tones covered in one head! I'm not sure what Doug has done but the preamps seem a little different than on the individual heads. The volumes are more linear, they come up smoother. Also with his effects loop, the HG preamp sounds so ridiculously sweet with something in the loop. Without anything in the loop the tone is more raw, very nice to be able to alter that crkt! The loop doesn't seem to affect the C80 crkt at all. There's also a man/wus switch (full/half power respectively) that changes things a bit obviously. To finish it off is a DI out with level adjust. Doug includes a footswitch but you can also change channels via a front panel toggle. Came loaded with Wing'd C's and JJ pre's. Nice compliment! Although, I've changed out the JJ's with a combo of Mullards and 9th gen Chinese (my fave). The workmanship is the best you'll find out there. What an incredible value this head is compared to other boutique heads out there...for me at least. I sure do like the Jenelle way better than the Wizard Modern Classic 100 I had. All I can say is...run, don't walk to get one of these! Thanks Doug!!!
