Features: My amp is a Herbert Mark II purchased last fall. We can all look at the specs on the website. I purchased mine new from Tone Merchants. I find it interesting that the last reviewer couldn't get support for his amp issues. I don't think Diezel should be blamed for user incompetence. The loops are the best I've ever used and the amp is great with most pedals. // 10
Sound: I really dig all three channels. Most people don't really change the settings enough to get an idea of all the capabilities of the amp. You really need to use the volume knob on the guitar to get an idea of the range of sounds available. I have a mix of guitars including: a Suhr Classic (P90,single,'bucker), G&L Comanche, 335, Reverends and a Les Paul. I've never played one amp that really gets along with all my guitars.
As far as noise, 60 cycle hum can be a little annoying with single coils in high gain mode--like any high gain amp. Noise on the power line can also be an issue. This is pretty typical of most amps.
The clean channel has a lot of headroom and really works well with overdrive pedals to add a bit of crunch. It will do that Hiwatt thing quite a bit. The second channel is an easy favorite. The -/+ switch really gives a lot of range. You can get tones from SRV, to Soldano SLO 100, Marshall and beyond.
The third channel is pretty wicked and can be unforgiving when playing sloppy. Attack is immediate and very punchy. I think that this channel needs to be experimented with to be fully appreciated. Don't just go for the really high gain dial in--roll the gain back a bit and see what you can get. I've sold all of my other amps because I'm totally satisfied with the Herbert. I like everything from blues to Nu metal and I think it handles all those genres well. // 10
Reliability & Durability: I think the amp is extremely well built. I'm kind of picky when it comes to design quality. It's built like a tank. Tubes are always the tricky part when it comes to amps. All than glowing glass needs to be treated right (standby/shutdown). Tubes are usually the problem in the few Herbert problems I've heard. // 10
Overall Impression: I don't think that there is a perfect amp for everyone. I've had Boogies, Top Hats, Bad Cats, and have access to just about everything out there. I think that the Herbert is one of the most versatile amps out there. The tones are incredible. I love a lot of different amps and will likely own others down the road, but I will never sell the Herbert. // 10
