So, I've had the '64 for a few days now.
So far it definitely makes both of my amps sound better using the amp out (Aguilar TH and GK MB), and actually works well for bringing the Fender sound to my guitar amps too! I've found I can finally get the highs I've always wanted out of my Tonehammer, and it made me realize the lows I was missing as well!
One note is when you crank up the highs w/ the amp out it can sort of sound brittle (or just high-mid scooped), but bringing up the mids really smooths things out in a nice way, not at all like the usual mid boosting sound. It's all very musical.
For recording I will definitely love the DI out for the very nice old-school warmth, and musical low end it brings. It does all 60s, lo-fi, etc. excellently. I probably won't use the DI (cab sim) for super hi-fi sounds as it does lose you some high end with the pedal/cab sim engaged. For that the amp out works nicely.
For live use I can't decide if I'll use it DI to board, because I don't yet know how many sound engineers will feel about the baked in tone of the cab sim. But I will at least bring it to either use for my (or backline) amp tone, or as a clean DI w/ the pedal off, if needed. For the rare in-ear gigs I do, I imagine the full preamp xlr w/ cab sim will be great.
Time will tell if live and studio engineers will love or hate the cab sim situation on these. I think they'll love the sound and low end content, but not sure since some are more used to dealing with the usual sterile DI sounds. Again, time will tell and I'm sure any good sound tech can work with it.
One thing I've noticed - there is a mild hiss from the amp out that increases with output/blend, and can be slightly remedied by using the 2k or 4k cut. Does anyone else notice this? Is it normal
@Origin_Effects ?
It's not worse than some effect pedals I own, just slightly annoying because it's heard through the amp, and DI from the amp which was previously totally silent. It is absolutely not noticeable in a mix, I'm just making sure it's not me, or my specific pedal having an issue. It does this powered with my 1 spot and mxr iso-brick, in case that's the problem.
Overall I'm loving this pedal, and can't wait to use it on upcoming shows and sessions. I'll try to remember to update with feedback I get from sound folks in the coming weeks.
