Congratulations on your purchase of the GT-5H.This is smaller amp head
made by Kailing electronic Co.,Ltd ( http://www.kldguitar.com). One 12ax7 is
preamp design and one 6l6 is power amplifier. The KLDguitar GT-5HA is a single
end Class A guitar tube head amplifier. It is 5w. This guitar amplifier makes
small-room sessions lots of fun! A higher-gain preamp circuit has been added to
take the overdrive tone beyond that of the original. A choice of High or Low gain
inputs are included. With a switchable Pentode/Triode, you get the only amp in
its class that can deliver the full tonal range from instantaneous punch to
deliciously creamy / crunchy overdrive, with precise control via the output
volume.
