TG will be talking to Opeth guitarists Mikael Åkerfeldt and Fredrik Åkesson at the Download festival and we want your guitar questions…
If you've got a question for Mikael and Fredrik let us know on Facebook or by e-mail.
Mikael and Fredrik are two of the most talented guitarists in progressive music - Opeth have long since transcended the 'metal' tag - so maybe you want to ask them advice on how to widen your playing horizons, the gear they rely on for their varied tones or how Mikael approaches songwriting.
Finally, remember we're a guitar mag, so although we may slip in a few general ones, if you ask a question about their guitar playing or songwriting, you're much more likely to get it answered.
If we pick your question, it will feature in a future issue of TG and you'll win a set of D'Addario guitar strings.
