Re: Laney amps?
I have not played the TT B2. But, i have to agree with those here on the GH. It is voiced in Marshall territory, but has that sizzle on the top end. It is not quite as upper-middy as the stereotypical modern Marshall, a bit more lower middy, a bit thicker. They have a bit of a Voxy topend, not spikey, more chimey. It is a one channel amp, with a foot switchable added gain stage, making it a bit difficult to get to a pure clean channel and a gain channel quickly.
The LC50 has tons more gain than the LC15, as the LC30 does also. The LC50 has the modern Laney voice I spoke of with the GH series, but in a smaller package.
Many Laney's are finicky to what tubes you put in them. Certain tubes can make them a bit fuzzy, certain tubes can make them overly bright.
