I found this old post which may help if it is still correct!
Recently I posted a thread on here about glass tips for Shakespeare rods as I was going to hybridise tips if it was possible, unfortunately it wasn't and decided to buy a separate rod and plumped for the Shakespeare mach 2 xt 10ft wand, it arrived yesterday, less than a day from ordering to arriving at the door.
On checking the tips I found the 1oz/30gm tip had a broken top eye, I phoned Amazon and set the ball in motion to have the tip replaced, FOC of course, and what helpful people I encountered, the rod originally came from Tacklemate but my complaint was dealt with by Fishing Republic and I spoke to a young lady by the name of Sarah, nothing seemed to be too much trouble and within a very short time it had been arranged for UPS to pick up the broken tip, any way, I phoned Fishing Republic to make sure I'd done the procedure correctly, yes, every thing was OK and now I just had to package the tip and wait for collection by UPS.
While I was talking to Sarah I asked if would be possible to keep the tip, or at least if they would be able to post it back to me as I'd be able to repair it myself and would have a spare tip, I was told to hold and then told to phone another number.
I spoke to a Kevin Pierce, apparently his company deals with all the warranty returns for Shakespeare rods and explained the situation, he checked through his stock and yes he'd got the tip I wanted and that he'd send me one free of charge.
I then phoned Fishing republic and explained what was happening and they said to cancel UPS and it was Job done, the reason for posting is the fact that the mach 2 wands have a very unusual base size on the tip, 3.05mm, so there are no generic tips to fit and I've noticed Shakespeare wand owners saying they can't get hold of them, now you can, £7.50 per tip plus P&P, all you have to do is google:-
K.P. Spares, they are in Studley Warwickshire, for all your Shakespeare rod spares.
