I am selling my almost new positive grid spark 40 guitar amplifier with modifications to run off of the supplied battery pack making it 100% portable. It also comes with the spark carry bag (as new)

I have only used this amp at home a couple of times just to test some of the available tones & it is absolutely outstanding & very loud, unfortunately that's why it's not suitable for me as I am a beginner guitarist teaching myself and this is just overkill for me as I only need a small desktop amp (I am now using the blackstar fly 3watt amp)

I bought this spark amp & immediately converted it to run on a battery pack to make it the ultimate portable amp which it definitely is but it is completely wasted on me. I probably shouldn't have bought it in the first place but I couldn't help myself as it looked so amazing.

Everything works 100% and will be provided with the battery pack with wire +the charger + original power supply and carry bag. Unfortunately I can't find the original box but if I do then it will be included.

To buy these same items online they generally retail for:

Spark amp 40 £299

Spark carry bag £30

Lithium ion battery pack £78 (amazon UK)

Please feel free to make an offer.

This is strictly collection only from Bristol Bs10 area.

UK bidders only, PayPal only, No refunds.

Thanks & good luck.

P. S battery is attached to rear of amp with magnetic strip
