🇺🇸【 Walrus Audio 】 ARP-87 Multi-Function Delay


ARP-87 是一款多功能 Delay 效果器,雖然身形細小,卻有4種不同模式:Digital、Analog、Lo-fi 及 Slap,可做出多種 Delay 效果。


■ Digital 模式能反射出原始、清晰的重複聲響,適用於節奏規律的樂句。


■ Analog 模式可以在不妨礙和絃及樂句的狀況下帶來溫度及空間感。


■ Lo-Fi 模式時,回聲的調變頻率是可以調整的,從溫暖、扭曲、朦朧,到AM廣播般的雜訊聲。


■ Slapback 模式讓您輕鬆調出 slap back 迴響,絕佳適應 chicken picking 等等風格。


■ 其他的特色包括軟式開關及暫時性漸強功能,ARP-87 有著無限創造的可能等著結他手們探索。X鈕會隨著不同模式的切換而改變它的作用,它在各個模式裡調整的是不同的特定參數。Digital、Analog、Slap 模式中X鈕所調整的是調變的深度,Lo-Fi 模式中X鈕調整的是濾波器的頻寬。需要注意的是,更改 Delay 模式同時也會套用到全新的運算方式,所以節拍的速度需要重新用 tap tempo 輸入。


■ Trails 尾音模式:ARP-87 可以選擇是否開啟尾音模式。在開啟尾音的狀態下關掉效果,Delay 的尾韻會延續,接著自然地消失。選擇沒有沒有的話,Delay 的尾韻會在關閉效果的同時瞬間消失。要在兩種模式間切換,在踏板連接電源時壓住 Bypass 開關一秒鐘、拔下電源,再次打開就能切換到另一個模式


■ Momentary Functions 暫時性功能:在關閉的狀態下踩住 Bypass 開關就能夠暫時性的開啟效果,為音色添加一點 Delay 的質感,放開以關閉效果。而在開啟 Delay 的狀態下踩住 Bypass 開關便會將X鈕的參數逐漸攀升至最大,放開開關就會讓所有數值回到按壓前的原始值。


■ 踩住 tap 開關會讓回授逐漸攀升至最強,放開後會掉回原始值。




The ARP-87 is a compact, feature-rich delay, packed with a large pallet of inspirational delay tones. Featuring four main algorithms, digital, analog, lo-fi, and slap back, the ARP-87 can cover some serious ground in the world of echoes. The Digital algorithm boasts pristine, crystal clear repeats great for rhythmic riffs. The Analog setting works well to add warmth and dimension to chords and lines without getting in the way. The Lo-Fi algorithm, with its adjustable frequency range on the repeats, goes from warm, warped, and murky, to strait AM radio. Finally, the Slap setting makes it easy to dial in a great slap back echo perfect for smoking chicken pickin’ runs. With other features like our smart bypass switching, and momentary knob ramp, the ARP-87 provides endless creative opportunities that are waiting to be explored.


The X knob changes functions depending on which Algorithm you are using. It adjusts a specific parameter in each algorithm. In Digital, Analog, and Slap modes, the knob will control modulation depth. In Lo-fi mode, the knob will control Filter width.


Note that when changing delay types this loads a whole new algorithm and the tempo must be tapped in again.


Trails Mode:


The ARP-87 can be run in trails or no trails mode. In trails mode, when you turn the pedal off, the delay trails die off naturally. In no trails mode, the delay trails are abruptly cut off when you turn the pedal off. To toggle between either mode, hold down the bypass switch for 1 second while applying power to the pedal. Unplug power and repeat to toggle to the other mode.


Momentary Functions:


When the switch is in off position, press and hold the Bypass Switch to temporarily activate the effect to add a moment of delay texture. Releasing the switch turns the effect off. When the effect is on, press and hold the bypass switch to momentarily ramp the X parameter to maximum. Releasing the switch sets the X parameter back to the knob location.


Press and hold the Tap Switch to temporarily ramp the feedback to maximum. Release to set the feedback back to the knob location.
