![]() The FX loop gets in between the two amp components, mean your pedals are only added after the pre-amp, preserving your tone and providing an arguably clearer signal. If you plug pedals into the front of your amp, those effects go through the preamp, thus compromising your precious tone. The pre-amp is what gives you your tone, and the power amp is what converts it into amplified sound. Most guitar amplifiers consist of a pre-amp and a power amp. It’s become a hugely popular feature on many modern guitar amps. As the term suggests, this means that your signal passes through the pedal totally uninterrupted – you can even remove a power source, and you’ll still be going! How does an FX loop work?Īn FX loop is another tool used by guitarists to ensure preservation of signal strength and clarity. A more popular option, wherever available, is a true bypass pedal. While this ensures that your signal remains clear and strong, it can also colour it slightly. The idea of buffered circuitry is give a slight boost to your tone, ensuring that any subsequent signal loss has been pre-preemptively accounted for. Plug in a cheap old overdrive pedal and leave it switched off – you might just hear a difference! What are buffered & true bypass pedals?īuffered & true bypass circuity is designed to combat any form of ‘tone suck’. It seems only natural that a signal running through all of that would be affected in some way, right? Some pedals have more going on inside, and many argue that pedals with cheaper components have more of a negative effect on your tone. Guitar pedals are a cocktail of capacitors, transistors, soldering and digital processing. #GUITAR EFFECTS SIGNAL PATH FULL#Mention it in a room full of guitarists and you’re in for a lengthy debate. #GUITAR EFFECTS SIGNAL PATH PROFESSIONAL#While there are possibly more professional terms to use, this is the one that gets thrown around most often. It’s the idea of losing some signal integrity by plugging a pedal / a number of pedals. Tone suck is a popular term for the very thing we’re trying to debunk. So what happens when you take a clear signal that runs from your guitar to your amp, and put loads of fun stuff in between? When you turn them on, it sounds great (unless they’re all fuzz pedals – that’s an acquired taste) but when you flick them back off, does your guitar sound the same? That’s what we’ll be exploring with this experiment. While there a number of variables to consider (which we’ll look into shortly), the main thing we’ll be analysing is the number of pedals used, and how that affects tone. While plugging a guitar into the front of a cranked up valve amp appeals to the no-frills rockstar inside each of us, the idea of sculpting your tone with a variety of stompboxes has proven an irresistible formula. Pedals have become more and more popular over the years, arguably for obvious reasons. We’ll be conducting a number of experiments to get to the bottom of this age-old tonal conundrum. So what’s the answer? Hypothesis: Having more pedals in your signal chain weakens your signal volume and quality. The idea of your tone being affected/diminished in some way by having a long signal chain with multiple stops along the way seems logical. You may have spent weeks, months or years tweaking your pedals to attain that sound you’ve been after, but what about when they’re bypassed? It’s long been a hot topic of discussion among guitarists and tone aficionados. There’s nothing we love more than an array of colourful effects and stompboxes that we can tap dance with! While some effects are designed to subtly improve your tone, there’s the occasional pedal that’ll warp your signal chain beyond recognition. You know how the old saying goes: you can never have too many pedals, right? Here at Andertons Music Co, we love pedals as much as the next player (or arguably more so). ![]()
