For sale is the pictured cab, it's a conversion from a marshall amp . It has a 12 inch speaker at 8 ohms, but I don't know the brand, reasonably, from searches I've done Marshall uses it in 50w amps. The power cable is connected to the speaker so no extra is needed as shown in the pictures. The cab is functional and has a focus on the treble/midrange, hence the "back" added to boost the bass a bit. Very honest for practice, rehearsal and experimentation! Besides, if one wants, one can replace the existing loudspeaker with an even better one to upgrade the cab.
Together with a 4-position multi-transducer, unfortunately I have 3 of the 4 cables. So it works for three pedals, and if one can find another adapter, it becomes for four.
Thanks!
