Listed 2 years ago
This is an IRIS 50 watt, EL34 based amp. It features jumpable inputs to blend the Bright and Normal Channels.
The controls on the amp are: Presence, Bass, Middle, Treble, Bright Volume and Normal Volume.
There is a preamp mode selector on the back of the amp. This 3-way toggle switch lets you choose from 3 different preamp modes.
The 3 Preamp Modes are:
1959 - Fender Tweed Bassman
1966 - Marshall JTM 45
1972 - Hiwatt Custom 100
By selecting the mode you want, the amp physically routes the signal to its own preamp circuit to give you the feel, dynamics and tone of the amp selected. The modes are NOT footswitchable. The overall output also changes from mode to mode. '59 mode has the most sag and lowest output, whereas the '72 mode has the most output, tightest low end and very low sag.
The amp also features Tube Rectifier (45 watt) and Solid State Rectifier (50 watt) modes to control the overall sag and tightness of the power amp.
There is also a Master Volume control on the back of the amp as well. This will allow you to crank the preamp gain, and still be able to play the amp at bedroom levels.
