![]() ![]() All the clips are recorded using bridge and neck pickups in parallel with split coils, making it essentially two single coil pickups in parallel. To answer these questions, I recorded a few audio clips playing the same riff with my new Bancika JPM guitar. So I a Xicon as well, partially to be able to go between “lo-fi” and “hi-fi” sounds and partially to demonstrate the differences between the two transformers and justify (or debunk) paying extra for a top shelf transformer from Lehle.Īnother feature I wanted to add is a switchable buffer, for two reasons: it can add color to the sound and be an “always on effect” in the signal chain and it can lower the impedance and potentially drive the transformers better. The one that seems the most suitable is Xicon 42TM018-RC 10K:10K transformer which costs a fraction of the price of Lehle, but has less desirable specs on paper, having the bandwidth of only 300 Hz to 3.4 kHz. They have a few different models with different winding ratios and impedances. I’ve seen some used for signal splitting, some can be used in Tycobrahe Octavia and sometimes even as cheap replacement for a wah inductor. While investigating transformers for this project, I remembered that Xicon small signal transformers are sometimes used in DIY projects because they are readily available and very cheap. I opted for the Lehle LTHZ (high impedance) isolation transformer which makes is a perfect candidate for DIY projects. ![]() Both have impressive specs and cost similarly (65 USD for Lehle and 75 USD for the Jensen). To best of my knowledge, Radial doesn’t sell transformers separately, only built into their products, so it’s down to Lehle and Jensen. Some of the most popular brands that come up when looking for quality transformers are Lehle, Jensen and Radial. ![]() So I got an idea – why not combine them into one device and build an ultimate recording utility? Both of those devices are built around audio isolation transformers that allow us to “break” the ground by galvanic isolation of input and output signal, avoiding noise caused by ground loops. Another utility that could be useful is a re-amp box that would allow passing the recorded dry signal back through the pedals and amps and record wet again, potentially with different amp settings and/or effects. Lehle Buffer/Splitter/Re-amp IntroductionĪs part of an effort to improve the quality of my home recordings, I realized that I’ll be needing a splitter box that can allow recording “wet” signal that comes from my amps/cabs as well as dry signal that I can manipulate further after it’s recorded. ![]()
