DO NOT attempt to buy any products from Silvertone Amp Covers and DO NOT use a payment provider trading under the name of NOCHEX. I ordered a cover for a MarkBass 151 P cabinet from Silvertone in September 2013. I received an email from NOCHEX, the payment provider, to acknowledge their receipt of my money. Since then, nothing, especially no delivery of the cover. I received no confirmation of order; I can't contact Silvertone because they have taken their website down, and NOCHEX have stopped replying to my questions as to the whereabouts of my money. I have no idea whether NOCHEX have simply banked the money or given it to Silvertone.
Only after having this problem did I think to check Silvertone Amp Covers' credentials and I found posts about them on BassChat from two years ago. I wish I had checked before I ordered.
