I collect premier harp amps and often I get them without knobs. I have accumulated a few spares from guitar shows and online auctions and I have paid anywhere from $3 to $7 for a knob. I was recently outbid on this set of knobs. I wanted them mainly because I don't have any yellow knobs. The knobs went for $12 each - $60 including postage.Things, as ever, are getting out of hand.
