Despite being incredibly sick, I was able to roll out of bed and go to the Post Office in order to pick up my set of Tiplop strings for my upright. I thought it was interesting that, even though Tiplop is in India, the package came via POS Malaysia Either way, I'm just glad they came via registered mail so there was no chance of them getting lost along the way. Speaking of which, according to eBay, delivery was estimated on March 15th at the earliest and these arrived on March 1st - nice! A little background on the strings/Tiplop: Tiptop is a company from India that specializes in making gut strings and gut tennis rackets. The site uses a stock pic identical to a pic on the Upton Bass site. The strings are incredibly cheap because, presumably, you are buying straight from the place of manufacture (ie there is no "middle man" to jack up the price). The site goes back and forth from hinting that they are either mutton serosa or cow gut (however, I have no idea how much of this is to be blamed on the language barrier). Here are the gauges of the Tiplop upright strings: E (4.5), A (3.7), D (2.8), and G (2.1). Mine were pretty close to those measurements. The day after I picked them up, I took them to KC Strings in Merriam Kansas and had them installed by a professional luthier. I loved the way they felt under my fingers (for both my left and right hand); however, there was just not enough tension on the E and A strings. It should be noted that my bass is a 5/8 with a 40.5" scale neck so that may have something to do with it. Honestly though, I don't see how adding another 1" to 1.25" would have helped. I left them on for a few days but - even though I really liked the D and G, I just couldn't stand the E and A. Today I took them off and did what the luthier suggested - re-install the E and A Innovation Psychoslaps in place of the E and A Tiplop guts. I just finished and - after adjusting the action, etc - I must say, it is a MAJOR improvement. Additionally, the D and G strings are so slim, I'm wondering if I should try replacing the G with the D, as well as the D with the A. The D is so especially slim I'm almost afraid to slap it However, right now, everything seems to be working out just fine. Overall, so far I'm satisfied with the Tiplop D and G strings but and very disappointed in the A and E. What's worse is that - even though the set only cost me $95 (including shipping) - if I had just bought the D and G set, I would have only paid about $30 (including shipping). I have no idea what to do with the E and A, and I'm not sure if Tiplop would accept those as a return. Speaking of the E and A guts being to flabby - is this normal or do more expensive gut strings usually not have this problem?
