Gear4music Oregon Neck Thru 4 string Bass Guitar. The guitar was an active/passive but has been converted to just a passive now. Kinsman K50B Bass Guitar Amplifier. 50 Watts output with a 10 inch speaker. Great sounding amp with plenty volume, has built in effects like Delay, Flanger, Chorus and Slapback. Although this is a bass guitar amp, I also think it makes a great 6 string guitar amp and sounds perfect for that use, which makes it a good home amplifier for someone who plays both bass and six string guitars. Both are in excellent condition with very little use and also included is a guitar stand and guitar lead. Bargain £160. No Texts.
