Are there any effect pedals that, once you'd made the original purchase, you went back to time and time again for replacements or to add to other pedal boards or in order to have the exact same pedal at different locations you keep equipment at? Pedals that once found cancelled out your need or desire to look for other examples of that particular effect. For myself ........ over long term usage ..... Chorus .... The Analogman Mini-Chorus with third external knob and fixed "deep" setting. It's the only chorus I use. I've owned two. One's over 10 years old and the other, on a separate pedal board, is seven years old. They both work as good as the day they were purchased. I'll stick with them forever. This is the most beautifully voiced vintage type analog chorus pedal I've ever found. Flanger .... The A/DA Voltage Controlled Flanger. I've owned the original AC plug in version as well as the 18 volt DC version that replaced it. Two AC versions and two 18 Volt versions. They sound the same to my ears. Neither are currently in production. I'll have to go used if I need any more. No other Flanger delivers the range or sweep settings of the A/DA. I've owned many Flangers and most either lack the range or are to complicated or noisy. Some effect the signal path in a bad way when they're not in use. The A/DA is the only one I'll use. Phaser .... The Mad Professor Hand Wired Tiny Orange Phaser. I've owned two. It's the only Phaser I've found that, with the turn of a dial, can create the best studio psychedelic phasing sounds from the late '60s / early '70s to the later harder rock / metal phasing sounds of the Phase 90 / EVH tones. At both ends of the spectrum it's perfect. Next to the Wah Wah and Echo / Delay the Phasing effect has always been my next favorite. I've owned more than I can count. From early MXR Phase 45s and 90s, A/DA Final Phase, Electro Harmonix Small Stone, Ibanez PT707 and PT9 right through the post 2000 Blackout Effectors Whetstone Analog Phaser. The Tiny Orange Phaser bests all of them to a degree that it's the only one I currently use. (of note* When I'm needing a third pedal board I'll still utilize the Whetstone Analog Phaser but will probably purchase a third Tiny Orange Phaser in the near future). Shimmer .... The Mr. Black Eterna Gold Modified. While their are multiple Reverb and Delay pedals that offer this effect as an option none of them have taken it to the state of perfection as the Eterna God Modified. It focuses strictly on the Shimmer effect. It adds a vocal like "choir" voice behind whatever you're playing. What makes the Eterna Gold Modified stand out from the rest is the way it never overpowers you guitars direct signal. It's also the only shimmer effect I've found that can sound absolutely beautiful when used during "lead" passages. When I first came across the "shimmer" effect, (on a strymon delay pedal), I liked it for rhythm work. I liked it a lot. The downside was the way it could crowd out thee main notes during a lead passage. It muddied things up. The Eterna Gold modified takes this flaw out of the mix. Combined with an Ernie Ball VP Jr. and a "violin" voiced gain pedal it produces an electric guitar voice that could front an orchestra.
