Up your budget just a little to £160 and bag yourself a Roland Cube 60- you always get your money's worth when it comes to music equipment that little financial extra bags you a whole lot more.
This amp is fab as it has all the qualities and flexibility of a good price amp but also drops in a multi-effects processor- some details below :
Powerful 60-watt output in a compact, 12-inch speaker design.
Built-in 9 COSM guitar amp models, including JC, British Combo and R-Fire.
New Dyna Amp feature offers expressive control over enhanced dynamics and tone transitions based on picking style.
Six classic built-in Roland effects, including Chorus, Flanger, Phaser, Tremolo and independent Delay/Reverb.
Multiple outputs, including Recording/Phones Out, Line Out, Tuner Out and Ext Speaker Out (for connecting external cabinets).
Channel switching, delay/reverb and effect on/off control via optional footswitch.
I've played this amp on long sessions and for over 2 years - it's a good'un
Vox amps are great sure, but not on the budget your looking for
edit/ I'd ask for dmpoole's opinion on this matter as I feel is probably the most experienced member on matters like this
