Gear Junkies have the scoop on this incredible (and vile) looking transparent Mellotron built by Streetly Electronics. They describe it as "a bespoke commission and a true realisation of a personal vision", and it's even been featured in stupid-rich-men's bible Robb Report. No word on which anonymous billionaire paid for it. Noel Gallagher bought this Mellotron a while back, so it's not him. If you must go transparent, go DIY.
