The PF is an awesome amp. AWESOME amp. From the wattage, to the tone, package, versatility, portability, d.i., recording, compressor, eq, and the cab. I love everything about it. I've tried the walkabouts. They too, are awesome. But the Ampeg just fits me.
The tonehammer is pretty bad ass. The main thing that I noticed is it's extremely versatile. From modern slap tones to old school stuff it's pretty dead on. I'll use the AGS circuit like P-ODDZ mentioned above. It'll be turned on for an entire song, not really mid song effect. But that's exactly why I wanted it. I play in four different bands. A huge band that plays old school dance, r and b, and light rock with a huge horn section, a cover band that plays nothing but 90s alternative, an all blues band, and modern country, southern rock, rootsey band.
So you can imagine why I'd want a little dirt here and there to emulate some rock tones, fatten up some trio blues, and to entertain myself now and then. Plus all the added benefits of recording and it being a di for live gigs and yadda yadda. I'm looking forward to playing with it.
As far as the AGS circuit and the whole purpose of this thread. lol. It's great!! It FATTENS the tone when it adds the "distortion", which in my experience is rare, and it's really easy to shape the tone. With just flat settings the thing does wonders for your sound. I'm excited. Thanks again for the help.
