The preamp is logically laid out–a single channel format with footswitchable gain, three-band EQ, volume, presence control and resonance switch. All designed to add to your guitar’s tone rather than getting in the way of it. Everything about the front panel compliment shouts simplicity and the only feature which might be new to a player is the Resonance Switch–which affects the damping response of the amplifier and hence the bass response. The rear panel of the GH50L offers you everything you need to interface your tone machine with out board gear – a selectable FX loop that can be set to work in three different modes depending on what you want to achieve. A selector switch determines which mode the FX loop operates in, either Bypassed, Series or Parallel. Wind the volume up and things become tonally very rich, lots of usable hi’s and lo’s and when you kick in the overdrive facility you immediately understand the magic in this range of heads – blistering high gain with tone to spare. Finished in Laney’s now famous livery and ergonomic side grab handles the GH50L looks every inch the tone monster it is.
