I am selling an Aguilar AG500 DC bass amplifier, 500W of power (at 4 Ohms), to see all the specifications, consult the internet or contact me, but I think it is a well-known amplifier, with a great sound and very good articulation. The model is dual channel, with a second saturation channel with a control to add distortion (with compensation system so that the output volume is constant) INCLUDES the pedal to change from one channel to another and to mute the amplifier , which in the end is how to have an overdrive pedal. It is racked in a transport bag which makes it very comfortable to transport (12kg total). The previous owner had it in a rack where it had to fit right in and it has scratches on the top from putting it in/out but they are not visible now that it is in the rack (but I'll warn you).
