Price and rating as shown on Amazon when we collected them. Both change.
The Marshall MG15GR is a 15-watt solid state practice combo with a single 8-inch speaker, reverb, an aux-in for playing music and a headphone out. It sits at number 5 in our guide to guitar amps, priced at £103 and rated 4.7 from 229 ratings. Marshall's own bullet points describe it as an "Ideal Practice Amp For Electric Guitar, 15 Watts" and list two channels, clean and overdrive.
Where the listing agrees with itself, we give it credit. 15 watts appears in both the bullet points and the specification table, and so does the 8-inch speaker — two numbers, two sources, so we treat them as fact rather than marketing. Where it does not agree: the bullet points advertise a "3 Band Equaliser", while the specification table gives Number of Bands as 6. The bullet points also say "2 Channels", while the table lists Output Channel Quantity as 1. Both figures come from the same listing, so we report both and let the buyer weigh them. Everything on this page is taken from the Amazon listing for this amp; we have not tested it ourselves.
