The Positive Grid Spark GO is number 9 in this guide. It is a 5-watt digital modelling amp and Bluetooth speaker in one, listed at £88.00 with 4.6 out of 5 from 4,303 ratings. Positive Grid calls it ultra-portable, and the cabinet dimensions support that: 12.4 cm deep, 8.4 cm wide, 4.3 cm high, in black plastic.

The speaker figure is where the listing stops adding up. The specifications claim a 15.24 cm speaker, which is six inches, while the cabinet is 12.4 cm deep and 8.4 cm wide — a driver that size does not fit in a box that size. The item weight is given as 1 g. And the tone count appears twice at two different values: the bullets offer 50,000+ tones from the ToneCloud community, while the item highlight on the same page says 100k+ tones. Where a number turns up twice at the same figure we give it credit — 5 watts appears in both the product name and the specification, so we take that one at face value. Everything here is taken from the Amazon listing, not from any testing of our own.

The bullets say 33 amps, 43 effects and 50,000+ tones from the ToneCloud community, plus custom presets. The item highlight on the same listing says 100k+ tones, so the two figures do not match.
