The DOD FX25 envelope filter pedal has become something of a cult classic – a simple, two-knob auto wah that gives bass players a variety of tones ranging from subtle vowel sounds to a full-on funk ‘quack’. The straightforward user interface and low price point make the FX25 a good starting point for bassists looking to experiment with envelope filters.
There are only two controls on the FX25:
Range controls the intensity of the filter effect
Sensitivity affects the point at which the effect becomes active (frequently labelled as ‘threshold’ on other envelope filters)
The sensitivity control allows the user to dial-in how subtle (or otherwise) they want the effect to be; as with all envelope filters, the FX25 responds to changes in your plucking hand dynamics and for this reason it’s wise to place it towards the front of your signal chain if you’re using multiple pedals. As all envelope filters and autowah effects react to changes in playing dynamics it’s important that any compression happens after the effect.
The FX25 was manufactured between 1982 and 1997, after which it was replaced by the FX25B; the main difference between the two is that the FX25B has an additional ‘blend’ knob.
The DOD FX25 is now sadly discontinued, but there are plenty floating about on eBay and other second hand gear sites. Here’s an overview of the pedal’s features and a demo of some of the sounds that it’s capable of producing, both on its own and in conjuction with other pedals including octave, fuzz, and distortion:
Part of the pedal’s popularity can be attributed to the fact that Flea used an FX25 during part of his ‘Adventures in Spontaneous Jamming and Techinques’ instructional video. It can be heard here during a jam with Red Hot Chili Peppers’ drummer Chad Smith:

The Electro Harmonix Bass Micro Synth gives bass players who are looking to dive into the murky waters of synth bass sounds an opportunity to access a range of classic synth tones without having to go anywhere near a keyboard. Although far more limited in its scope than more recent synth pedals, like the Future Impact or the Source Audio C4, the intuitive control layout of the Bass Micro Synth means that bass players can start experimenting with sounds almost instantly without having to delve into complex sub-menus:
The Bass Micro Synth is controlled by numerous sliders that govern the following parameters:
Trigger affects the dynamic level at which the effect is triggered; this can be thought of as ‘sensitivity’ or ‘threshold’. The trigger only affects parameters in the filter sweep section of the pedal
Sub Octave controls the level of the 1-octave down signal
Guitar affects the dry signal volume of the bass
Octave controls the volume of the 1-octave up signal (the octave above signal is slightly distorted to provide a richer tone)
Square Wave affects the volume of the square wave distortion
Attack Delay increases or decreases the time taken for a note to reach full volume. Higher settings can remove the intial attack from notes, resulting in a ‘bowed’ sound
Resonance controls the intensity of the filter sweep
Start Frequency and Stop Frequency govern the frequencies at which the filter sweep starts and stops; different settings can result in ‘up’ or ‘down’ sweeps
Rate controls the speed at which the filter sweeps between the start and stop frequencies
If the range of controls on the bass microsynth seems daunting then don’t panic; EHX also publish a pdf of sample settings (link here: EHX Micro Synth Sample Templates PDF) that lets you get straight to the good stuff without hours of unnecessary knob-twiddling. I went through all their tone templates to see what the pedal is capable of:

Uh-oh, it’s another post about gear.
The main questions that you might have are:

What the hell does this have to do with Fight Club?
Both of these can be answered by watching the following gear-orientated soliloquy:
T.H.Palmer’s famous self-esteem poem advises ‘If at first you don’t succeed then try, try again’, which is exactly what I’m doing in an attempt to confront my own gear addiction. For the back story on my struggles with gear hoarding, take a look at the post that started it all, The Gear Fallacy.
Having failed spectacularly to keep my 2016 resolution of not purchasing any new equipment I decided to give it another shot and, at the time of writing, I’ve been ‘clean’ for almost 6 months.
But I haven’t won my battle yet. I’m still confounded by what I’ve named ‘The Gear Paradox’.
What the hell is ‘The Gear Paradox’?
Just when you thought that I couldn’t be any more pretentious I drop this on you. I’m sorry.
Simply put, The Gear Paradox expresses the difficulty in reconciling the knowledge that fixating over gear is a waste of time with the desire to have an appropriate sound for every musical situation, which necessitates a certain amount of attention to detail when it comes to equipment.
I don’t yet have a solution to this conundrum, but here are some facts ideas that have helped me to work out how I feel about gear and manage my addictive, equipment-hoarding tendencies. Maybe some of these will ring true for you:
90% of ‘your’ sound is down to you: your fingers, your technique, your sense of time, your harmonic knowledge and how ‘big’ your ears are. Gear accounts for only 10%. Many players invert these percentages and perpetually change their basses/strings/pickups/amps/pedals in an attempt to solve problems in their playing.
There is a perception that possessing rare or expensive gear somehow makes you a better player. This is exacerbated by the superficial nature of image-based social media platforms that allow us to engage in a perpetual show of one-upmanship and endlessly fixate on what others have rather than focusing on our own progress.
Your band and your audience don’t care about your gear – they want you to show up on time, play the right notes and make everyone in the room feel good; if you can’t fulfil those 3 objectives then the type of magnets used in your pickups really pales into insignificance.
One analogy about the importance of gear (or lack thereof) is from world class producer/arranger/writer/educator Richard Niles (I couldn’t find the original quote so I’m paraphrasing, but the essence is the same):
“It doesn’t matter whether you’re making music with a guitar, a bass or a computer – it’s the music that’s important. It’s like having a delicious meal in a restaurant and asking the chef what sort of spoon they used to stir the soup.”
Stop worrying about spoons and instead work out what ingredients are missing from your soup.
(Your soup might already have all the right ingredients, it just needs to simmer for longer).
What’s The Best Bass For Metal?
This nebulous question (and others in a similar vein) crops up again and again across the length and breadth of the internet. I’ve lost count of the number of times I’ve seen the comments underneath virtuoso bass performances asking questions about what brand of strings or which pickups the player is using – the phrase ‘barking up the wrong tree’ doesn’t even come close.
Sax supremo Bob Reynolds deals with this far more eloquently than I ever will:
Contrary to what the internet would like you to believe you don’t become a great Gospel player because your headstock has ‘MTD’ on it, you don’t get the bass chair on a show in a London theatre by owning an Overwater and having a multi-scale fanned-fret Dingwall won’t make your metal playing any heavier.
There is no substitute for doing the work; I say this as someone who, in spite of 17 years of playing, still has a TON of work to do and avoids doing it by writing blog posts and filming silly videos. Do as I say, not as I do.
